xAI details persistent multi-session agent architecture for Grok Bot including chat history, roster, dedicated compute, and autonomous task initiation.

Versions of OpenAI's ChatGPT and SpaceXAI's Grok will join Google's Gemini on the Pentagon's central portal for AI tools.

xAI accused of training Grok on real and AI-generated child pornography.

Deep learning classifier for appendicitis severity grading in ultrasound images using Grad-CAM explainability; domain-specific medical imaging application.

Deep Neural Networks (DNNs) deployed in high-risk domains, such as healthcare and autonomous driving, must be not only accurate but also understandable to ensure user trust. In real-world computer vision tasks, these models often operate on complex images containing background noise and are heavily annotated. To make such models explainable, Concept-based Explainable AI (CXAI) methods need to be assessed for their applicability and problem-solving capacity. In this work, we explore CXAI use cases in multi-label classification by training two DNNs, VGG16 and ResNet50, on the 20 most annotated ...

Congrats to the team!

AI teammate category just had its most significant new entrant yet

You’ll have to be fine with letting Grok sign into your online accounts, however. | Image: SpaceXAI SpaceXAI has introduced Grok Bot, an always-on AI agent service designed to behave like independent "AI teammates" that can do your work for you. The bots share their own cloud-based computer environment, and can sign into apps, tools, and websites you already use to complete multi-step workplace tasks, only coming back when their assigned work is completed or if something requires approval. Grok Bot (or Bots, as SpaceXAI inconsistently pluralizes it) is the latest push from Elon Musk's AI comp...

River AI, a startup founded by xAI co-founder Igor Babuschkin, has a fascinating vision for personal agents and secured $1.1 billion out of the gate.

This paper addresses the limitations of Explainable Artificial Intelligence (XAI) with respect to insufficient evaluation. They are illustrated through the DetoxAI image recognition system for bias detection and concept unlearning. Then, an example of a human-grounded evaluation of methods for explaining image classification is presented. The paper further explores methods for adapting explanations to evolving data streams with concept drift. Experiences with adapting counterfactuals for this problem are discussed. Finally it is related to the challenges of tracking the co-evolution of data, ...

xAI's Grokipedia, an online encyclopedia with AI-generated articles that Elon Musk once promised would be a "massive improvement" over Wikipedia, apparently hasn't been updated since April 24th, according to a report from Lawfare. "As far as we can tell, no entry has changed in more than three months," Lawfare said. Grokipedia launched in v0.1 in October 2025 with an initial batch of 885,000 articles, and is now on v0.2 (released in November 2025) and has more than 6,000,000 total articles, according to grokipedia.com/live. But that live page also has a section titled "Recent changes to…" wit...

Privatize the profit, socialize the losses? | Image: Cath Virginia / The Verge, Getty Images Once, I had some questions about why SpaceX, Elon Musk's healthiest company, acquired xAI, his sickliest one. Now I have some questions about why we're calling the whole thing SpaceX. Look, what we have here, by revenue, is primarily a telecom company and a company that rents compute, according to SpaceX's first quarterly earnings statement as a public company. The space sector of the business didn't break a billion dollars this quarter and contributed only a touch over 10 percent of the company's rev...

SpaceX has ramped up its purchases of Tesla Megapacks for its xAI data centers.

PipeNetwork/minimax-h3-mlx MiniMax released MiniMax-H3 two days ago - they describe it as a "a general-purpose, omni-modal generative system", which in practice means it accepts text, images, audio and video and can use them to generate up to 15 second video clips with audio included. This Python package ports it to MLX for running on Apple Silicon. I got it running on my M5 Max MacBook Pro. I cloned the repo and ran the model like this: # First download the models uvx --from huggingface_hub hf download MiniMaxAI/MiniMax-H3 \ --include 'FL2VA/*' --exclude 'FL2VA/transformer/*' uvx --from hugg...

Despite a lawsuit from xAI, a Minnesota ban on apps that allow users to “nudify” images can move forward.

Introduces EPC score metric for evaluating XAI explanation fidelity by balancing feature sparsity and model performance preservation.

SpaceX is building a new power plant for xAI's Colossus data centers, but it won't remove existing, unpermitted turbines for many more months.

xAI is suing Minnesota Attorney General Keith Ellison over a law passed back in May that broadly targets "nudification" apps, claiming that the statute's punitive provisions leave the company with "no practical choice but to restrict Grok Imagine's image-editing features in various ways." The law, the company argues, violates the First Amendment. Back in January, Grok flooded the internet with millions of sexually explicit deepfakes, including images of minors. In another era, a content moderation disaster of this magnitude would have had the CEO flipping the kill switch on the product within...

xAI's grok-build CLI tool uploaded entire directories to Google Cloud without consent; xAI responded with data deletion after community backlash.

The Elon Musk-owned xAI is suing a South Carolina man who allegedly used the company's Grok AI chatbot to generate child sexual abuse material (CSAM). In a lawsuit reported earlier by Reuters, xAI claims Terry Wayne Harwood "knowingly and intentionally used Grok to circumvent safeguards, alter nonconsensual images, and generate and distribute CSAM," breaching the company's policies. Harwood was arrested in February for allegedly possessing and distributing CSAM and is facing eight felony charges. The lawsuit claims "at least some" of the images related to Harwood's criminal charges "were gene...

SpaceXAI's Grok Build AI coding tool was spotted uploading users' entire codebases to Google Cloud before it was reported, and the company turned it off. The Register reports that Cereblab published findings on Monday showing how the Grok Build CLI was packaging and uploading entire code repositories, "including files it was told not to open and secrets deleted from history," significantly more data retention than similar tools like Claude Code. The researchers say that as of Monday, their tests show SpaceXAI's servers returning a "disable_codebase_upload: true" flag, and the codebase upload ...
